Answer:
Some islands have older islands at one end of the chain and younger islands at the other end. Example is the Hawaiian Islands.
Explanation:
Volcanic mountains or islands are formed when the tectonic plates in the earth’s crust converges. The string of Hawaiian volcanic islands were formed as a result of the movement of the Pacific plate over a fixed hotspot, where the magma rises upward and erupts on the seafloor. The northwestern islands are older than the islands to the southeast side of the Hawaiian islands.
The age of a volcanic rock is calculated by measuring the amount of argon and the amount of radioactive potassium present in the rock. These measurements are the supporting evidence which showed that the southeastern end of the chain is younger than the northwestern part of the chain. The volcanic islands gradually subside and erode as they age, so the older islands have much lower elevations than the newer islands. This is another evidence which supports the conclusion.
Answer:
The correct option is <u>C:</u> Posterior clinoid processes and dorsum sellae.
Explanation:
An Anteroposterior (AP) axial projection (Towne method) is a <em>radiograph of the skull</em> used to evaluate and demonstrate the <em>presence or state of fractures</em>.
Structures that can be seen are the entire <u>occipital bone</u>, the <u>petrous part of the pyramids</u>, and the <em>foramen magnum</em>. Through this last one, there can be seen the dorsum sellae and the posterior clinoid processes.
When the sea floor spreads or collides it creates breakages which would be ocean ridges and deep sea trenches
Answer:
Through genetic modification/engineering
Explanation:
<em>Most of the species that we use as food do not look like their ancestral species anymore because humans have genetically modified them to suit their desires.</em>
Through genetic engineering, humans have been able to select desirable characteristics or attribute from one organism and transfer it to another organism of similar species that already has some desirable attributes. Thus, the latter organism becomes genetically modified and looks different from its ancestors just to suit the taste of man.
